. APPARATUS FOR BURNING QIL.

SPECIFICATION forming part of Letters Patent No. 735,441, dated August 4, 1903.

Original application filed August 2, 1900, Serial No. 25,713. Divided and this application filed September 28, 1900. Serial No. 31,420.- (No model.)

T at whom it may concern Be it known that I, GEORGE L. BADGER, of

Quincy,in the county of Norfolk and State or.

7 Massachusetts, have invented anewand useful Improvement in an Apparatus for Burning Oil, of which the following, taken'in conism shown in the accompanying drawings, in

Which Figure 1 is a vertical section through the burner. Fig. 2 is a horizontal section taken on line 2 2 of Fig. 1, the division-plate A being omitted. Fig. 3 is a horizontal section taken on line 3 3 of Fig. l.

The base or lower part of the casing of my. burner is indicated by A, provided with an annular wall A A, to which is attached'a plate A A Below this plate A A a series of perforations a a are made for the admission of air into the lower or sub compartment S, in whichis located the mechanism for causing and controlling the mixing of air with the heated oil-vapor and also mixing-chan1bers 5 L and M, from which the oil-vapor and air pass through openings in the division-plate A to the concentric heating-chambers S S S S -that is, the space between the divisionplate A A and the fire-plate B B B B. In 0 these concentric heating-chambers S S S S the mixture formed in the lower chambersL and M becomes of such a nature as to be completely combustible previous to its passage through the perforated plate B B B B into 5 the combustion-chamber S Oil is drawn from any suitable source throughthe pipe 0 and made to flow through" the coil 0 G? to the pipe 0 Thence it passes downward to the horizontal pipe 0 Figs. 1

and 3, which delivers it in the form of vapor throughthe small orifices E E E E E into the open cone-shaped injector-nozzles placed in multiple series, (see F F F E, Fig. 3,) to which air is supplied at their mouths and also through the openings H H. As the commingled oil-vapor and air leaves the primary nozzles F F it passes into a second set of similar injector-nozzles F F and gathers additional air from the mouths of the second nozzles and also from the openings H H. The mixture now flows through the contracted passages K (which,-in fact, constitute other injectori nozzles) into the inductiontubes K K K K.

Thence the mixture passes from'the tubes K into the mixing-chambers L L, from which it flows upward into the outer one S of the con centric heating-chambers S S (See Figs. 1 and 2.)

The oil-vapor that jets from the orifice E passes through injector-tubes similar in all respects to those already described (F and F) into the induction-tube K which is like the tube K,already described, and discharges into the central mixing-chamber M and thence to the inner concentric heating'chamber S (see Figs. 1 and 2,) where the mixture becomes ready for complete combustion. The

volume of vapor and air now being thoroughly mixed and heated to a high temperature I passes through the perforations D and D into thecombustion-chamber above the plate B and immediately beneath the boiler or thing to be heated.

The combustion-chamber S is annular in horizontal section. The inner wall is shown at A and the outer wall'at A (Se'eFigs. 1 and 2.) Both of the walls are perforated, as indicated by b b. A third wall A incloses the whole and-is closed at the topby the plate A and at the bottom by a register device S S so that the amount of air admitted to the space S and thence through the outer perforated wall A can be regulated or cut ofi altogether, as may be desired. The inner air-space S has a closed top and a register botto'mV V, the movable part of which is operated by a lever V and any suitable connections. By the register devices just described the inlet of air to the combustionchamber S may be regulated. at will or entirely cut off.

The oil-vapor inlets E E E E E, Fig. 3, are opened and closed by needlevalves R R R R R, respectively. These needle-valves pass through protecting-tubes N N. The four needle-valves R are attached directly to the cross-bar R and are operated by the lever B", which is connected by the link R to the bracket-piece A and is adapted to actuate the bar B through the sliding rod R head R and pivot R The needle-valve R is indirectly connected to the bar R by means of the short bar R and steady-rods r r. The sliding rod R rotates and is turned by the hand-Wheel R. Its longitudinal motion is limited by the collar R between the arms of the bracket A Screw-threads t t are out upon the ends of the rod R the screw at one end being a right-hand one and at the other end a left-hand one, so that by turning the rod by the hand-wheel R the distance between the head-block R and the short bar R and the attached needle-valve R can be 4 adjustedthat is, the needle-valve R can be so adjusted as to have the opening E open after the other openings E E E E are closed by their respective needle-valves R R R B. By this device the flow of mixed vapor and air through the central tube K to the cham+ ber M and thence to the perforations D D can be maintained after the flow through the tubes K K K K to the chamber L L and the perforations D D is cut ofl.

If desirable, the sliding part 8 of the register device S 5 may be connected by the pivot T link T, adjusting-nut T and link T to the lever B", so that the air-supply may be governed by the same lever that regulates the vapor-supply. can be so adjusted that the air passing through the perforations b b in the wall A may be cut ofl entirely while the vapor mixture is burning and opened only'whcn it is desired to cool off the apparatus, or any other desirable adjustment may be made to adapt the burner for special purposes.

For the purpose of lighting my burner I have the following-described device: W is a can having a supply of alcohol or some similar fluid, and W is a pipe provided with a suitable stop-cock (not shown) and leading to the annular depression W in the perforated fire-plate B B. By allowing a small quantity of alcohol or other similar fluid to flow into this depression and igniting it heat is generated about the pipe 0 0' C and the contained oil is converted into vapor and forced through the pipes C C to the orifices E E E E E and after taking up the desired amount of air passes into the combustionchamber S where it will become ignited and maintain an intense heat about the coil 0 O and thus develop great heating power. In

the meantime the starting-fire in the depression W can be allowed to go out, as the This controlling device burner supplies its own generating power from the oil within the pipes as it flows from the source of supply, where it is kept under some pressure or head.

The system of working this apparatus may be set forth as follows: The oil (kerosene) flows in through the pipe 0 and is heated in the coil 0 C so as to form a vapor which passes down the pipe 0 and is discharged from the pipe 0 into the mixing apparatus in the subchamber; The mixture of air and vapor passes into the mixing-chambers L L and M in the subchamber S and from there upward through the openings in the plate A A into the concentric heating-chambersS' S where it receives additional heat from the intense flame above the fire-plate B B. Thence it passes through the perforations D D D into the combustion-chamber S S By delivering the oil-vapor after it has been generated in the receptacle, through a series of small orifices and arranging in connection with each of these small orifices a needlevalve and a separate group of air-injectors, each group embodying a primary nozzle and one or more secondary nozzles, as shown in Figs. 1 and 3, a larger quantity of oil may be vaporized, the vapor mixed with sufficient air and supplied to the combustion-chamber than can be done by any devise now in use. This division of the oil-vapor by a series of orifices and connecting with each orifice groups of air-injectors is an essential feature of my apparatus and gives it an advantage over any known device, inasmuch that the relative proportion of air to the oil-vapor will remain nearly constant regardless of the total amount of vapor and air supplied to the combustion-chamber.
